Most people think polenta is complicated to make. However, polenta is pretty easy to make, especially if you make it in an Instant Pot. Best of all, you only have to stir the Instant Pot Polenta once, seal the pot and let it cook. To make the polenta more flavorful, we cooked it in low sodium vegetable broth, then stirred it in vegan butter, nutritional yeast to give it a cheesy flavor, and vegan shredded cheddar cheese. Finally, to complete this dish, we cooked sliced button mushrooms in vegetable broth, then sautéed them in olive oil, garlic, and shallots before placing them on top of the perfectly cooked polenta. And there you have it, the ultimate vegan comfort food! 

What is the ratio of instant polenta to water?

The ratio for cooking polenta is 1 cup of polenta to 4 cups of water. However, since the polenta is being cooked in the instant pot, the balance is 5 cups of water to 1 cup of polenta.   

Is instant polenta the same as polenta?

Instant pot polenta is not the same as regular polenta. Instant pot polenta cooks in a few minutes. In contrast, traditional polenta may take 30-40 minutes to cook. In addition, instant polenta is not as flavorful as regular polenta.   

Do you need to soak polenta before cooking?

Wet polenta is not necessary. However, soaking the polenta does reduce the cooking time. In addition, drinking the polenta helps rehydrate it, making it cook faster. Nevertheless, whether you choose to soak polenta is up to you.   

Why does my polenta stick to the pan?

The polenta will stick to the pan if it is not stirred, so stir your polenta every 4-5 minutes to prevent it from sticking to the bottom of the pan.
